Africa’s Green Revolution threatens traditional foods

New research argues that AGRA's two-decade push for commercial seeds, fertilisers and a maize-centred Green Revolution has expanded monoculture acreage while undermining production of traditional, climate-resilient African crops. The study finds modest maize yield gains in many participant countries accompanied by large increases in maize area and declines in staples such as millet, cassava and groundnuts.

Africa’s Green Revolution threatens traditional foods

Why It Matters

The shift toward subsidised, market-oriented monocultures may weaken food-system resilience and reduce diet diversity at a time when climate change and conflict are already driving hunger increases across Africa. Loss of locally adapted crops risks eroding seed diversity, farming knowledge and nutritional options for rural communities.

Key Facts

AGRA anniversary: AGRA marked its 20th anniversary in 2026 (launched 2006).
Maize yield change: Average maize yields rose about 40% over 18 years in participant countries, below AGRA's 100% target.
Undernourishment trend: In countries with substantial AGRA presence, the number of undernourished people increased ~60%, similar to the continental rate.
Maize area expansion: Land allocated to maize increased 71% in participating countries since 2006.
Millet production decline: Millet production fell 27% and millet yields dropped 17% since 2006; land for millet fell 12%.

Researchers examining the effects of the donor-funded Alliance for a Green Revolution in Africa (AGRA) report that the initiative’s promotion of commercial seeds, fertilisers and market-oriented crops has driven a pronounced shift toward monocultures—most notably maize—across many participant countries. While AGRA frames its mission as sustainably growing Africa’s food systems, the study finds that the policy mix favoured by the programme has coincided with large increases in land devoted to maize and only modest yield gains, falling short of the substantial productivity improvements originally promised. The research documents that maize area more than doubled in the countries studied, largely fueled by subsidies and investments, yet yield growth averaged roughly 40% over 18 years rather than the 100% improvement AGRA targeted. Some individual countries—such as Malawi and Ethiopia—saw stronger maize yield growth, but others, including Kenya, experienced declines. At the same time, production and investment in traditional staples have waned: cassava productivity across 13 participant countries fell 21% and groundnut productivity declined 10% since AGRA’s launch. Millet emerged as the most affected traditional crop. Before AGRA’s programme expansion, millet occupied a similar share of production as maize in these countries; since 2006 millet production has dropped 27%, yields are down 17%, and land under millet has fallen about 12% while maize area rose 71%. The authors stress millet’s advantages—heat and drought tolerance, low input needs and nutritional value—highlighted by the FAO’s 2023 “Year of Millets.” The study’s authors argue that substituting diverse, locally adapted crops with commercially promoted monocrops reduces farmers’ options and heightens vulnerability to climate shocks, pests and supply disruptions. They call for investment and policies that support farmers’ rights to save, use and exchange seeds, protect crop diversity and ensure communities retain agency over which varieties are cultivated. The researchers say AGRA and other promoters still prioritise improved, certified varieties and market-oriented seed systems, and they urge donors and governments to stop subsidising crops that contribute to the loss of agricultural diversity.
